Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.
Hi Hao Bo, I suspect your problem is caused by "nRows = 1". Your grid is probably really the product of numbers of rows and columns both significantly larger than 1. You need to use these values, rather than setting nRows = 1 and nCols = the number of points in your grid. Rather, you need to factor the number of grid points into nRows * nCols where both are > 1. Good luck, Bill
